Application led September 16, 19GB. Serial No. 453,232.

To all whom it may concern:

' Be it known that i, JOHANN Gonirnn'r Pn- 'rEnsoN, a citizen ot the United States, residing at Hartford-in the county oi l-'iarti'erd and State of Connecticut, have inven new and useiul Electricwitch Rccep oi" which the 'following is a speciiication.

This invention'relates to those receptacles which are designed to receive push button electricswitclies, and moreparticularly to those push button receptacles which are niade of insulating material and have a hutton guiding and "face plate attaching traine or bar extendingacross the open end and a sheet oi insulation closing the open end.

The object of the invention is to provide a receptacle ci this nature with a very simple,

easilyforrned, and quickly assembled means for closingv the open end, whereby, in a cheap manner, the interior can'be protected from the entrance ot' dust and dirt, particularly plaster and the like, as when the receptacle 1s set in an uniinished wall and before the "face plate is applied, which covering and pro* tecting means thoroughly insulates the tace plate and eliminates any possibility of the end ot a conductingwire from which the insulation is removed where it is atta ched to a contact post by a binding screw, from loosening or springing up and making Contact `with i the face plate, l

The invention resides in a receptacle ot' insulating material having a bar extending across its open end and a sheet of insulating material so shaped that it-can be quicllyu placed over the open end of the receptacle and snapped into engagement with the bar in such manner that it will hold in place against accidental removal without other fastening devices, yet can be instantly removed when desired to permit access to the interior of the receptacle for wiring and v other purposes.

Figure 1 of the, accompanying drawings shows a front view lof a push button switch. Fig. 2 shows a view ofthe saine with the face late omitted. Fig. 3 shows a plan with the ace plate and insulating cover omitted Fig. l shows aplan ci the insulating cover. Fig. 5 shows a plan of the bar that extends across the'open end of the receptacle for the attachment .of the face plate and for guiding the push buttons. Fi G is a central longitudinal section taken t rough the face plate, bar and insulatingcover for the receptacl tod a ceptacle.

`and causing a short circuit.

The receptacle l shown is one ofthe rece tangular ty .e, usually made of porcelain. iith this form of receptacle' the insulated circuit wires are brought up' the outside of the end walls near the corners and the bared end oi the wires bent inward through grooves inthe upper edges and wound around screws 2, which are threaded into the binding posts 3 that are fastened in the interior of the re- The bar eis placed across the open end oi the receptacle and fastened. This bar is vusually perforated for the push buttons 5 and tor the screws G that hold it in place, and also for the screws 7 that secure the plate S in position. The perforated sections oi the bar shown are joined by a narrow section 9. y

The cover 10, which is cut from a sheet ci insulating paper, iiber7 or the like, has an ex terior contour approximately of such shape that it iits into the rabbeted upper edges oi the side walls of the receptacle. The cover shown is out out so' as to substantially contorni to and iit the outline of the bar, eX- cept that the distance between the sections il is somewhat less than the width oi the section that joins the perforated portions of the` bar. This provides two tongues which, when the cover is placed in position over the open end oi the receptacle, can be snapped beneath the narrow section ofthe bar in such manner as to securely hold the cover in place. The cover can be quickly removed from the receptacle by bending the tongues from beneath the narrow section oi the bar.

`When the cover is in place it closes thereceptacleand prevents the entranceV oi dust and dirt. This is oi particular value whenl;

lining for the face plate and eliminates any danger of the bare ends of the conducting. wires 'from springing up, or ofthe binding screws from working loose and getting into contact with the inner surface oi the plate Such a. cover as is herein described is very cheap toniake and it can be' easily and quickly appliedor removed as desired. j

The invention. claimed isi. The. combination with the insulating base oi' an electric switch receptacle, of a bar l extending across the open end of the receptacle, and an insulating coverclosing the'open end ofthe receptacle, said cover having tongues lthat project beneath portions of the b'afr so as to hold the cover in place, substan K tially as speeied.

2 The combination withl Fthe insulating f'an electric switch receptacle, of a bar exte ding across the open end of the lrecepf *"tacle, said bar being perforated for the pasf- .jo' sage ofl push butto cover closing the' open end of thel receptacle, said cover tongues Aat its center that 'project beneath the portion ofthe bar be? tween the-button peiforations so as to hold i515 the cover in place, substantially as specified.

3.v The combination with the insulating ns, and @insulating tacle, said bar lbeirig'perforated for the pas#I sage of push buttons, an insulating cover ,clos-4 lng the open end ofthe receptacle, said cover havlng tongues at lits center that project be .-,fneath the portion of the bar between thebute ton perorations and a face plate secured tol -fthe bar and insulated from the interior of the receptacle by said cover, substantially as specified; l Y
